Van De Loo said he was checking the boy for a condition he believed he may have, but went about it the wrong way.

Van De Loo said he should have just sent the boy to a urologist, and saved the boy and his family a lot of stress.

The defense built their case throughout the testimony, spending most of the morning focusing on Dr. Van Le Loo's educational background and training, and his adherence to proper procedures in the exam room.

Van De Loo said during his career he has given thousands of routine physical exams.

Van De Loo was asked if there was ever a time where he had given a genitourinary exam, which is a full exam of the genitals, without a medical reason for doing so, to which he replied no.

Fifteen young boys have taken the stand over the last eight days, each testifying that during physical examinations and genitourinary exams, Van De Loo touched them inappropriately.

The prosecution has stated that Van De Loo's actions were for sexual gratification, while the defense claims they were simply part of the medical procedure.

Van De Loo was asked on the stand today if when he touched the boys, he did so for sexual gratification, to which he replied he did not.

Van De Loo admits he made mistakes when it came to handling the exam with the sixteen year old boy who made the initial allegations of sexual assault.

"Doc, what were you thinking?"I wasn't thinking, I was thinking that I need to make this diagnosis and I didn't stop to think what { the patients } perception of this was. " said Van De Loo.

Van De Loo said he should have done the exam differently and said he would not do it again because he quote "made a mistake"

The defense has possibly six to eight more witnesses to call.

They say closing arguments could be heard on Wednesday before the case is turned over to the jury.

Dr. David Van De Loo is facing charges of sexually assaulting fifteen boys who were his patients.

The trial was moved to Douglas County after Van De Loo's attorney, Rich White, filed a change of venue request due to extensive media coverage in Eau Claire.
